Coleus plant named ‘SAKCOL023’

ABSTRACT

A coleus plant particularly distinguished by a multicolored leaf pattern of bright rose foliage with dark burgundy blotches and venation, and green margins, with a mounding plant habit and small leaves, is disclosed.

Genus and species: Solenostemon sp.

Variety denomination: ‘SAKCOL023’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of coleus,botanically known as Solenostemon sp., and hereinafter referred to bythe variety name ‘SAKCOL023’.

‘SAKCOL023’ originated from the open pollination of 8 unpatentedproprietary lines crossed pollinated in October 2014 in Kakegawa, Japan.The breeder put breeding materials ‘14P-202’, ‘14P-203’, ‘14P-205’,‘14P-210’, ‘14P-211’, ‘14P-212’, ‘14F-19’, and ‘14F-20-2’ in a cage.Bees then crossed them at random. The breeder harvested 1,200 seeds from‘14P-211’. These seeds were composed of hybrid seeds and self-pollinatedseeds.

The seeds obtained from the ‘14P-211’ plant were sown and a single plantselection designated ‘L2015-CO258’ was selected for its multicoloredleaf pattern with a bright rose foliage with dark burgundy blotches andvenation, and green margins with mounding plant habit with small leaves.The breeder confirmed that ‘L2015-CO258’ was fixed and stable.‘L2015-CO258’ was subsequently named ‘SAKCOL023’.

The new plant was first asexually propagated from October 2015 to April2016 in Japan and has been asexually reproduced by vegetative cuttingsfor almost three years in Japan. The present invention has been found toretain its distinctive characteristics through successive asexualpropagations by vegetative cuttings.

‘SAKCOL023’ has not been made publicly available or sold more than oneyear prior to the filing date of this application.

SUMMARY OF THE NEW PLANT

The following are the most outstanding and distinguishingcharacteristics of the new variety when grown under normal horticulturalpractices in Salinas, Calif.

-   -   1. Small leaves; and    -   2. Bright rose foliage with dark burgundy blotches and venation        and green margins.

DESCRIPTION OF THE PHOTOGRAPHS

This new coleus plant is illustrated by the accompanying photographwhich shows the overall plant habit and foliage of a plant aged 3 monthsold. The colors are as true as can be reasonably obtained byconventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctivecharacteristics of ‘SAKCOL023’. The data which defines thesecharacteristics were collected from plants grown three months fromtransplant into 4-inch pots from rooted cuttings in Salinas, Calif.,under greenhouse conditions.

King, Cambridge University Press.

The vegetative    cuttings were propagated for five to six weeks. The base of the    cuttings were dipped for 1 to 2 seconds in a 1:9 solution of Dip 'N    Grow (1 solution: 9 water) root inducing solution immediately prior    to sticking into the cell trays. Cuttings were stuck into plastic    cell trays having 98 cells, and containing a moistened peat    moss-based growing medium. The cuttings were misted with water from    overhead for 10 seconds every 30 minutes until sufficient roots were    formed. Rooted cuttings were transplanted and grown in 20 cm    diameter plastic pots in a glass greenhouse located in Salinas,    Calif. Pots contained a peat moss-based growing medium. Soluble    fertilizer containing 20% nitrogen, 10% phosphorus and 20% potassium    was applied once a day or every other day by overhead irrigation.    Pots were top-dressed with a dry, slow release fertilizer containing    20% nitrogen, 10% phosphorus and 18% potassium.
